Hi hardi ! Sorry to reply so late... I didn't notice you put a comment ... So to to give more info, it's just a simple exercice that I give to complete for my colleague when I teach then how to model /design a product on CAD. I give a short description of the insights and they do have to design it to fulfill the needs. This one is one I have done for example and I take an artistic licence to design the clamps, because it doesn't need to be so complex ;) Thanks again for nice comment and sorry for a so long reply.

Benjamin, thanks for the insights. I think it would be very interesting to participate in your class.

muito bom!parabéns!
